MAURICE R. HORRELL, OF CHANUTE, KANSAS, ASSIGNOR OF TWO-THIRDS TO THEWESTERN DRLLING TOOL & SUPPLY CO., OF CHANUTE, KANSS.

OPERATING MEMBER.

Application led September 14, 1925. Serial No. 56,298.

To all whom it may concern:

Be it known that I, MAURICE R. HoRRnLL, a citizen of the United States,residing at Chanute, in the county of Neosho and State of Kansas, haveinvented a new and useful Operating Member, of which the following is aspecification.

This invention aims to provide novel means for holding an operating rodor member in adjusted longitudinal positions, the device being ofpeculiar utility in connection with the clutch-operating rods of a welldrilling machine, although the device is capable of general application.

In the drawing z-Figure 1 is an elevation. Figure 2 is a plan, Figure 3is a sec tion about on the line 3-3 of Figure 1, the operating memberhaving been operated through an arc of about 90, Figure 4 is a sectionon the line 4-4 of Figure 3, the tooth.y however, being in the positionof Figure 1, Figure 5 is a section on'the line 5 5 of'Figure 3, the rodbeing omitted, and Figure 6 is an elevation showing a slightmodification.

The numeral 1 marks a support or standard which may have a transversefoot 2 at its lower end, lif the support is to be secured at 3 to theupper surface of a part 4; but

y if the support is to be fastened to the side of an object, the support5 (Figure 6) may have a transverse shoulder 6 and a reduced lower end 7.

At its upper end, the support 1 is provided with a laterally extendedhead 8 wherein an opening 9 is formed, the opening having a reducedupward extensionlO. The inner edge of the head 8 has downwardlyconverging surfaces 11, and in the sides of the head, below the surfaces11 there are seats 12 'which taper inwardly.

An operating member or rod 14 is mount ed for longitudinal slidingmovement, and for rotation, in the opening 9 of the head 8, and carriesa handle 15. The operating rod 14 is provided with outstandingprojections 16 having sloping or converging surfaces 17 defining reducededges 18 shaped to conform to the seat 12.

In practical operation, the rod 14 is rotated from the position ofFigure 1 to the position of Figure 3 so that the projections 16 are inline with the extension 10 of the opening 9 in the head 8. The rod 14then can be slid endwise for adjustment. Assuming that the rod is in theposition of Figure 3, the rod is rotated, and one of the slopingsurfaces 17 of the rod rides along one of the inclined surfaces 11, theprojerw tion ultimately being lodged in one of the seats 12. Owing tothe duplication of the inclined surfaces 11, of the seats 12, and of thesurfaces 17 of the projection 16 of the operating member 14, the saidmember will be held in place regardless of whether the force exerted onthe member 14 is exerted to the right or to the left in Figure 1, itbeing possible to engage the projection 16 in either of the seats 12shown in Figure 4.

I claim z- 1. A device of the class described, comprising a supporthaving an opening provided with an extension, an operating rod slidableand rotatable in the opening and having a lateral projection adapte-d topass through the extension, the support having a seat wherein theprojection is adapted to be lodged, the support having an inclinedsurface over which the projection rides when the operating rod isrotated to engage the projection in the seat.

2. In a device of the class described, a support having an openingprovided with an extension, an operating rod slidable and rotatable inthe openingv and having a lateral projection adapted to pass through theextension, the support having seats which are duplicated at oppositesides of the support, the support having converging inclined surfacesover either of which the projection rides when the rod is rotated toengage the projection in either seat.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature.

MAURICE n. HORREL'L.
